1. The effects of two abundant ant species on soil nutrients and seedling recruitment in Brazilian Atlantic Forest
ABSTRACT Ants can influence soil fertility and the spatial distribution of seeds, with possible effects on seedling recruitment. The ant species Pachycondyla striata Fr. Smith, 1858 and Odontomachus chelifer (Latreille, 1802) co-occur in many forest areas in the Neotropics. We assessed soil fertility and seed bank structure in soil samples close and distant

2. Spectrophotometric Determination of Aluminium in Hemodialysis Water
A spectrophotometric method for the determination of AlIII in hemodialysis water employing alizarin red S complexing agent in the presence of polyvinylpyrrolidone 40 surfactant is described. The complex, formed in pH 4.5 buffered media, is detected at 510 nm. Optimal concentrations of all reagents were investigated as well as the appropriate detection wavele

3. Improvement of Soft Tooling Process Through Particle Reinforcement with Polyurethane Mould
Use of conventional flexible polymeric mould materials yields to longer solidification time of (wax/plastic) patterns in soft tooling process, thereby reducing the rapidity of the process to a great extent, which is not desirable in present competitive market. In this work, approach of particle-reinforcement with mould materials is introduced to reduce the c

4. Ativação de filme de hexametildisiloxano com o uso de plasma de baixa pressão e radiação UV / Activation of hexamethyldisiloxane films with low pressure plasma and UV radiation
The development of clean and efficient technologies to replace traditional methods for solid metallic or polymeric surface treatment in processes related to adhesion is a very important area of research. Plasma treatment and ultraviolet radiation are an altemative to accomplish these objectives since they generate very little residues, can be easily manipula

5. "Estudo comaparativo das densidades radiográficas de diferentes filmes periapicais obtidas por meio da análise computadorizada em valores de alumínio-equivalente" / Comparison of radiographic densities from different dental intraoral x-ray films by computed analysis into aluminium-equivalent values
RESUMO O objetivo deste estudo foi obter as densidades radiográficas de diferentes filmes periapicais por meio de um programa computadorizado que utiliza a imagem equivalente em alumínio (alumínio-equivalente). Avaliaram-se os filmes Agfa Dentus M2 Comfort, Kodak InSight, Kodak Ektaspeed Plus, Kodak Ultra-speed e Kodak D. Todos foram expostos aos raio

6. Construção e testes de máquina de ensaio de torção plástica para levantamento do comportamento plástico de metais
A computerized prototype machine for cold torsion testing has been developed, constructed and tested in the Laboratory of Metal Forming at UDESC (University the State the Santa Catarina) - Joinville. The equipment consists of a horizontal torsion machine, employing an electric motor, a wheel, a horizontal axle and a control and acquisition data system. The g

7. O banco de sementes de um fragmento de floresta estacional semidecidual no municipio de Campinas, SP
The characterization of seed banks is an important subsidy to the conservationist action in forests. The main objective of this dissertation was to examine the soil under the canopy of Santa Genebra Forest (22°49 S 47°06 W Campinas, SP. For the presence of viable seeds by, sieving, air fluxing and sprouting seedling techniques. Samples of 900ml of soil(Eig

8. Experimental aluminium encephalopathy: quantitative EEG analysis of aluminium bioavailability.
Single oral doses of aluminium hydroxide (50 to 200 mg/kg) were found to induce in mice a dose-dependent diminution of the power of the 7.5 to 12 Hz frequency band, with a parallel dose-dependent increase of aluminium content in the brain, as early as 45 min after administration, and indicated that aluminium hydroxide is readily absorbed through an empty sto
